[0005] Preferably, the frame has positioning posts at the four corners inside, and the positioning posts have insertion holes in the middle. The bottom of the frame cover is provided with a positioning rod that is inserted into the insertion holes.

[0006] Preferably, the frame is provided with symmetrical mounting platforms for mounting the circuit board inside.

[0007] Preferably, the snap-fit ​​assembly includes a guide groove provided on the inner wall of the frame, a snap-fit ​​interface opened at the bottom of the guide groove, and a snap-fit ​​plate snap-fitted into the bottom of the frame cover with the snap-fit ​​interface.

[0008] Preferably, the snap-fit ​​plate includes a deformable portion and a snap-fit ​​portion.

[0009] Preferably, the wire clamping assembly includes a wire clamping block one detachably provided at the bottom of the wire insertion port, a wire clamping block two provided at the bottom of the frame cover corresponding to the wire clamping block one, a plurality of guide holes provided at the top of the frame cover, a guide rod provided through the guide holes and connected to the wire clamping block two, a reset spring sleeved on the outer circular wall of the guide rod, and a limiting plate connected to the top of the guide rod.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4This utility model provides a protective lead frame assembly, including a frame 1, a detachable cover 2 on the top of the frame 1, a circuit board 3 installed in the frame 1, a snap-fit ​​assembly 4 installed on the frame 1 and the cover 2, a wire-passing port 5 on the side of the frame 1, a wire clamping assembly 6 on the wire-passing port 5, and symmetrical grooves 7 on the side of the cover 2. An operator can guide the cover 2 by squeezing the snap-fit ​​plate 43 along the corresponding wire groove, causing the positioning rod 10 to engage with the insertion hole 9, and the snap-fit ​​part 432 of the snap-fit ​​plate 43 to engage with the snap-fit ​​interface 42. This allows for easy installation of the cover 2 onto the top of the frame 1. Simultaneously, the lead wire passing through the wire-passing port 5 and connecting to the circuit board 3 is clamped by the wire clamping block 61 and the wire clamping block 62 in the wire clamping assembly 6, preventing the lead wire from falling out of the frame 1 when pulled by external force, thus improving the protection of the lead wire and increasing the practicality of the equipment.

[0020] like Figure 2 As shown, specifically, the frame 1 has positioning posts 8 at its four corners, and the positioning posts 8 have insertion holes 9 in the middle. The bottom of the frame cover 2 is provided with a positioning rod 10 that is inserted into the insertion holes 9. When installing the frame cover 2, the positioning rod 10 is inserted into the insertion holes 9 to further improve the ease of installation of the frame cover 2 and the frame 1.

[0021] Specifically, the frame 1 is symmetrically provided with mounting platforms 11 for mounting the circuit board 3, which facilitates the fixed installation of the circuit board 3.

[0022] like Figure 3 As shown, specifically, the snap-fit ​​assembly 4 includes a guide groove 41 provided on the inner wall of the frame 1, a snap-fit ​​interface 42 opened at the bottom of the guide groove 41, and a snap-fit ​​plate 43 snap-fitted to the bottom of the frame cover 2 and the snap-fit ​​interface 42. By guiding and sliding the snap-fit ​​plate 43 along the wire groove, and making the snap-fit ​​plate 43 snap-fitted with the snap-fit ​​interface 42, the frame cover 2 can be conveniently installed on the top of the frame 1.

[0023] Specifically, the snap-fit ​​plate 43 includes a deformable part 431 and a snap-fit ​​part 432. By squeezing the snap-fit ​​part 432 of the snap-fit ​​plate 43, the deformable part 431 is driven to deform, thereby facilitating the movement of the snap-fit ​​part 432 along the wire groove and engaging with the snap-fit ​​interface 42 to fix the frame cover 2 on one side of the frame body 1. Similarly, by squeezing the snap-fit ​​part 432, the deformable part 431 is deformed, causing the snap-fit ​​part 432 to disengage from the snap-fit ​​interface 42, and the frame cover 2 can be easily disassembled with the groove 7 for easy maintenance.

[0024] like Figure 4As shown, specifically, the wire clamping assembly 6 includes a wire clamping block 61 detachably mounted at the bottom of the wire insertion port 5, a wire clamping block 62 corresponding to the wire clamping block 61 at the bottom of the frame cover 2, and a plurality of guide holes 63 at the top of the frame cover 2. A guide rod 64 is provided through the guide holes 63 and connected to the wire clamping block 62. A reset spring 65 is sleeved on the outer circular wall of the guide rod 64, and a limiting plate 66 is connected to the top of the guide rod 64. Before installing the frame cover 2, the plurality of lead wires passing through the wire insertion port 5 are first overlapped into the corresponding arc-shaped groove 12. As the frame cover 2 is continuously installed, the wire clamping block 62 squeezes the reset spring 65, and the guide rod 64 slides along the guide hole 63. Finally, it cooperates with the wire clamping block 61 to clamp the lead wire into the arc-shaped groove 12, preventing the lead wire from being pulled off by external force.

[0025] Specifically, wire clamping block 1 61 and wire clamping block 2 62 can be replaced according to the diameter of the lead wire to improve the practicality of the equipment.

[0026] Specifically, both the first clamping block 61 and the second clamping block 62 have several arc-shaped grooves 12 on their sides. The arc-shaped grooves 12 are provided with anti-slip pads 13. The anti-slip pads 13 further increase the friction after the lead wire is clamped, prevent the lead wire from rotating in the arc-shaped grooves 12, and further prevent damage to the lead wire sheath.

[0027] Specifically, the top of the frame cover 2 is provided with a transparent plate 14, which facilitates further observation of the state inside the frame 1.

[0028] The working principle of this utility model is as follows: In use, the operator slides the snap-fit ​​plate 43 of the frame cover 2 along the corresponding wire groove by squeezing it, so that the positioning rod 10 is inserted into the insertion hole 9. The snap-fit ​​part 432 of the snap-fit ​​plate 43 is snap-fitted into the snap-fit ​​interface 42, which facilitates the installation of the frame cover 2 onto the top of the frame 1. At the same time, the lead wires passing through the wire through the wire hole 5 and connecting to the circuit board 3 are clamped by the wire clamping block 61 and the wire clamping block 62, which prevents the lead wires from falling out of the frame 1 when they are pulled by external forces, thus improving the protection effect of the lead wires and increasing the practicality of the equipment.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
